3 Claims. (01. 28533) 7 This invention relates generally to drains, and more particularly tozadjustable drain connections. I

All drains of this character made according to the priorart, and with which we are familiar,

have been very difficult to install and very unsatisfactory after installation because the openings in the surfaces to be drained arenot ordi- .narily in alignment with the fixed drain pipe. This difiiculty'is encountered particularly in urinals where a plurality of drains are connected to a main drain pipe, the upper portions of the drain connections fitting into openings in the bases of. the urinals. All work in connecting the "main drain pipe withthe openings in the surfaces to be drained must be done after the surfaces are set in place thereby making the task for installation very difficult because many of the openings are off-set laterally with relation to the main drain pipe. Some manufacturers have tried to remedy this difficult problem by providing fillers, wedges, annular rings and the like but it was found impossible to work through the openings of the surface to be drained;

It is, accordingly, an object of this invention to overcome the above defects, andmore parv ticularly to provide a means for compensating for the off-set between the openings in a surface to be drained and a main drain pipe having multiple drain connections between said openings and said main drain pipe.

- Another object of our invention is to provide an adjustable drain connection which has more than one point of adjustment.

-Another object of our invention is to provide means for adjusting the drain connections between the main drain pipe-and the openings in the surface to be drained.

Another object of our'invention isto provide an adjustable drain connection between a main drain pipe and an opening in a surface to be drained which may be operated through the opening in the surface to be drained.

Another object of our invention is to provide an adjustable drain connection which also provides support for the surface to be drained.

Another object of our invention is to provide an adjustable drain connection which is simple in construction, cheap in cost, efiicient in operation, and easy to install.

Other objects of our invention will become evident from the following detailed description,

taken in conjunction with the accompanying drawing, inwhich broken away in section of a urinal with our novel adjustable drain connection installed.

Fig. 2 is a sectional view taken on the line 2-2 of' Fig. 3 showing the limits of the adjustable movement of the strainer head byfdash lines.

Fig. 3 is a plan View of our novel adjustable 'dr'a inconnectionvwith the strainer head removed.

-.n-al I embedded at its base in a cementitious material 2 and having an opening 3 with tapered sides 4 for receiving the strainer head 5. It

will be apparent that although we have shown and described our adjustable drain connection in connection with urinals, they may be used in and with any surface to be drained such as shower baths or any other use where drains are required, especially where a multiplicity of drains are connected to a main drain pipe.

Coming now to the gist of the present inven-. tion, a base plate 6 is shown embedded in the cementitious material 2, the base plate 6 having a centrally located threaded opening I for threadably engaging the threaded pipe 8 leading to the main drain pipe 9. An annular member Ill extends upwardly from the base plate 6 and is integral therewith although it will be'evident that the member ID may be connected to the base plate 6 by any suitable means. A threaded portion H is provided on the upper end of the annular member H] for engagement with a threaded collar [2 which supports the. heavyweight of the urinal. An inwardly pro jecting threaded portion l3 threadably engages a threaded circular plate M which is disposed eccentrically with relation to a cylindrical connecting portion l5. Fig. 5 shows a modified construction in which the connecting portion [5a is threadably engaged to the circular plate '40,. The strainer head 5 threadably engages the upper end of theconnecting portion l5 and with its tapered seating portion I6 is eccentrically disposed with relationto the axis of the connecting portion I5. Lugs I! are provided on the connecting portion l5 and spanner wrench holes I8 on the strainer head 5' in order that the strainer head 5 and the; connecting portion l5 with the circular plate l4 may be rotated independently from the opening in'the surface tobe drained. b I In the installation of our noveladju'stable drain connection, the main drain pipe 9 and the base plate 6 with its upwardly extending annular member I!) is embedded in a fixed position. Ordinarily urinals and the like are disposed in units of more than one therefore requiring a. plurality of drain connections to the main drain pipe. After the required number of connections to the main drain pipe are provided for, the threaded circular plates l4 with their cylindrical connecting portions l5 are engaged to the threaded projecting portions l3 and the urinals or any other surface to be drained are set in place carried by the collars 12 on the annular members I0. .Since the positions of the openings 3 in the urinals l vary somewhat because of the processes in their manufacture, many of the openings 3 are ofi-set considerably from the connections leading from the fixed drain pipe 9. The strainer heads 5 are then engaged to the upper end of the connecting portions I5 and moved to a seating position with relation to the tapered sides 4 in the openings 3. Since both the strainer heads 5 with their seating surfaces l6 and the circularplates M are eccentrio to the connecting portions l5 and are adapted to move independent of each other, they may both be rotated, one through the lugs 11 and the strainer head 5 through the holes l8, until the seating surface I 6 of the strainer head 5 seats perfectly on the tapered sides 4 in the openings 3. Any form of material may be used to form a seal between the seating portions l6 of the strainer heads 5 and the tapered sides 4 of the openings 3. Although the descriptionof the installation refers to a multiple drain connection where a plurality of drain connections are required, it is evident that it will apply to a single drain connection.

It will be apparent that we have provided an ad justable drain connection which may be operated from an opening in the surface to be drained, which is simple and durable, which provides support for the surface to be drained, and which compensates for any oif-set between the main drain pipe and the openings in the surface to be drained.

Various changes may be made in the specific embodiment of the present invention without departing from the spirit thereof, or from the appended claims.

What we claim is:

1. In an adjustable drain connection, in combination, a base member having an internally threaded circularflange portion, an extended adjusting nipple having a threaded eccentrically disposed flange on one end thereof in engagement with the threaded portion of said base member,

and a strainer head having an eccentrically disposed opening in engagement with the other end of said nipple.

2. A claim as claimed in claim'liwherein an adjustable support is disposed on said base member.

3. In an adjustable drain connection, in combination, a base member, an internally threaded circular flange portion disposed on said base member, an extended adjusting nipple having a threaded relatively movable eccentrically disposed flange on one end thereof in engagement with the threaded portion of said circular flange portion, and a strainer head having an eccentrically disposed opening in engagement with the other end of said nipple.
